Depending on mission requirements, a typical fireteam consists of 4 or fewer members; an assistant automatic rifleman, an automatic rifleman, a rifleman, and a designated team leader; the role of each fireteam leader is to ensure the fireteam operates as a cohesive unit.
Recent studies suggest that green tea catechins may reduce the amount of glucose that passes through the intestine and into the bloodstream. This will benefit diabetics by preventing blood-sugar spikes when tea is taken with meals.
But in healthy volunteers in Japan, they tested what the same high fat meal did when eaten while drinking black tea (green tea is believed by some to be even better) and while drinking water. The tea group had better blood flow and higher antioxidant levels in their blood (that's good because it prevents damage). So, the tea seemed to be balancing out the damage and probably lowering the risk of a heart attack. Instant tea probably won't work.
